Modern monitors use Display Data Channel aka DDC for monitor detection/communication.

Slightly off-topic: DDC 2B is I²C based which makes modern VGA ports useful for external interfacing to various devices. See also VGA (VESA DDC).

So look for a VBE (VESA BIOS Extensions) DCC related extension which will most likely be what you will need to call to change to an external monitor. Or for an easy option try already having an external monitor powered up/fully plugged in and then power up the laptop but immediately close the laptop's lid to force the BIOS startup routines to find the active external monitor via the DDC (I²C) bus instead of what will be an inactive internal monitor (also on the same bus but inactive as closing most lids makes it inactive - unless you've changed that via a BIOS which sometimes exist). If you get stuck Google VGA BIOS DDC for more info etc.
